It seems that some SCSI drivers can block while the spinlock on a given
disk queue is being held. Work around this by dropping the lock before
bdev_strategy(), and re-grabbing the lock afterwards. This is a
temporary measure until I get to gutting this queue locking code.
There has been some success with this in addressing PR#39993.
This patch is from Antti Kantee. Thanks!
